Two two-way solenoid valve works

Two two-way solenoid valve for the direct action of step-by-step solenoid valve can be opened and closed according to the state of power off, can be divided into normally closed solenoid valve and normally open solenoid valve. Normally closed solenoid valve, the coil is energized, the armature in the electromagnetic force under the action of the first deputy to bring the valve plug lift, the main valve on the flow of the valve cup flow through the deputy valve to reduce the role of the pressure in the main valve cup, when the main valve When the pressure on the valve cup is reduced to a certain value, the armature will drive the main valve cup and use the pressure differential to open the main valve cup and the medium will flow. After the coil is de-energized, the electromagnetic force disappears and the armature is reset by its own weight. At the same time rely on media pressure, the main valve to be close close. Normally open solenoid valve, the coil energized due to suction, move the iron core down, the deputy valve plug pressed, deputy valve closed, the main valve cup cup pressure rises, when the pressure rises to a certain value, the main valve cup The same pressure up and down, due to the role of electromagnetic force, moving the core to promote the main valve cup, the main valve seat pressure, the valve closed. Coil power, the electromagnetic suction is zero, the deputy valve plunger and moving core uplift due to the action of the spring, the deputy valve is open, the main valve on the flow of the valve cup flow through the deputy valve to reduce the role in the main valve cup Of the pressure, when the pressure on the main valve cup reduced to a certain value, the use of pressure to push the main valve cup, the solenoid valve is opened, the media flow.

Cup magnetic assemblies, also known as round cup magnets, RB Magnets or Magnetic cup assembly round Countersunk Magnet.  Cup magnet can be used for a wide range of applications where a strong attractive force is required. Surface of round cup magnet is plated with nicuni surface treatment and have good anti-corrosion effect, thus it also could be used in outdoor environment. The highest operate temperature is 80 ℃(176 ℉,high temperature will decrease its magnetism and please avoid do it.

Cup magnets can hold object without scratching. excellent for attaching signs to automobile.Constructed of a steel cup with a Neodymium Magnet assembled inside, the round magnetic cups have a countersink or axial hole provided for easy fixing. Available with neodymium magnets or Ferrite Magnet configure inside the cup. The Neodymium magnet types have a countersink, hole for fixing with a screw head.

Cup magnets are commonly used for situation They are brilliant for lifting, holding and positioning purposes for indicators,antennas, inspection equipment, furniture fixings, gate latches, closing mechanisms & soft drawer closures, DIY projects, machinery, vehicles...

Cup magnet provide high magnetic strength at low cost.  RB magnets are often found in applications requiring a strong holding device or the ability to attach a post or hook to hang other items. 

Configure magnets with steel cup to increases strength dramatically ( by concentrating magnetic flux to multiplying the attractive force)Common usage is for holding Sign and banner mounts,Channel letter guides,Latches,Work Holders,Hooks and Hangers,Point of Sale Display component.
